A More Simple G-Code Programming within an Open Source CNC System
2006
In this paper we introduce the utilization of a new CNC programming language, named O-Word, a way to implement several branching routines into the EMC interpreter. It opens new interesting possibilities to programmers who can build subroutines, loops, and conditionals while taking advantage of the interpreter's use of variables and computation. Therefore, it allows us to make pieces describing theirs features instead of tool's movements. We will demonstrate a new complex routine in order to show both the language syntax and its potential for advanced applications.
INTERNET BASED DEVELOPMENT OF AN OPEN SOURCE LOW-COST CNC
2006
In this paper we show how to realize a low-cost numerical system, based on an “open source” software called EMC (Enhanced Machine Control). First, we assembled a low cost CNC workstation with a remote control by means of an online computer with a webcam, as an example of the software's potentiality. Moreover, we translated a graphical user interface (AXIS), in co-operation with the international development community, in order to improve its userfriendliness.
A Web based remote control of CNC machines
2009
Due to the large variety of products in small batch sizes, a modern machining shop floor requires an advanced real-time control system able to both monitor all the features and adapt the manufacturing system to the rapid changes of production capability and functionality. This is especially true when the shop floors are combined with the e-Manufacturing concept. e-Manufacturing is a transformation system which enables the manufacturing operations to achieve a predictive near-zero-downtime performance as well as to synchronize with the management systems through the use of infotronics technologies (i.e., wireless connections, web applications, networking systems, etc.). In recent years, the …
Low‐cost, High‐Capability, Embedded Systems for CNC Education and Research
2015
Teaching of CNC and CAD/CAM technologies has recently taken a great importance, due to their development, to the great number of solutions available on the market, and to the frequent updates. Nevertheless, one of the most urgent need is to improve the quality of education coping with a rapidly growing number of students. Nowadays, in comparison to the past, many Open-Source technical solutions, both hardware and software, are available to realise easily and cheaply some scaled-down prototypes of numerical control machine tools: these are able to work perfectly and can be employed as a learning method. This paper shows some past experiences regarding the development of some degree thesis wo…
UN SIT PER IL PPE DEL CENTRO STORICO DI PALERMO: IL CASO STUDIO DEL MANDAMENTO CASTELLAMMARE
2015
In this work a Geographic Information System was realised at the service of municipal administration of Palermo, to integrate, manage and store city plan information regarding the urban district Castellammare whereof detailed executive plan of inner city, correlating basic cartography, current urban instrument, cadastral cartography, current restriction schemes, monumental and historical monuments, street numbers and street network. Quantum GIS vers. 1.8 of Free and Open-Source Software (FOSS) community was exclusively utilized to the fulfilment of GIS. To the experimentation and the fulfilment of WebGIS a free server was used in cloud on the Amazon, where a virtual machine, based on MapSer…
OPETH: Open Source Solution for Real-Time Peri-Event Time Histogram Based on Open Ephys
2019
Single cell electrophysiology remains one of the most widely used approaches of systems neuroscience. Decisions made by the experimenter during electrophysiology recording largely determine recording quality, duration of the project and value of the collected data. Therefore, online feedback aiding these decisions can lower monetary and time investment, and substantially speed up projects as well as allow novel studies otherwise not possible due to prohibitively low throughput. Real-time feedback is especially important in studies that involve optogenetic cell type identification by enabling a systematic search for neurons of interest. However, such tools are scarce and limited to costly co…
Izšķirošās IKT izvēles nākamās digitālās dekādes robežšķirtnē Latvijas skolu izglītības politikas veidošanas sistēmā : promocijas darbs Vadības dokto…
2008
Darbā aplūkotas vairākas izšķirošas izvēles, kuras ir jāveic Latvijas izglītības sistēmai tuvākajos gados sakarā ar pasaules ieiešanu nākamajā digitālajā dekādē, ko pavada ne tikai būtiskas datoru infrastruktūras un lietojumu izmaiņas, bet arī pārmaiņas visā sabiedrībā kopumā, tajā skaitā vadības metodēs, koncepcijās un, līdz ar to arī izglītības sfērā un izglītības vadībā (IV) it īpaši. Darbs veltīts šo pārmaiņu teorētiskajai un praktiskajai bāzei, īpašu uzmanību pievēršot atklātā pirmkoda programmatūras (APP) lietošanas iespējām un aspektiem mācību procesā Latvijas skolās, galveno uzmanību pievēršot operētājsistēmu, biroja programmatūras un interneta risinājumu, tajā skaitā e-mācību, izvē…
La educación en Ciberciudadanía Responsable
2017
Resumen: Ante el fortalecimiento del papel de la tecnologia en la sociedad actual, se hace necesario pensar el rol de aquella desde un punto de vista mas radical, examinando el fenomeno mismo y sus consecuencias. La Filosofia tiene un papel fundamental a la hora de examinar y proponer alternativas educativas que contemplen las particularidades del proceso formativo del individuo y su papel como ciudadano en una sociedad profundamente mediada por la tecnologia. Partiendo de las afirmaciones de algunos autores como Chomsky, Benkler, Prensky, Ortega y Gasset, Habermas y, especialmente, Hans Jonas, propongo el concepto de “Ciberciudanania Responsable” como marco critico del Homo Tecnologicus, c…
Cumulative innovation, open source, and distance to frontier
2020
We develop a multistage game in which firms do cumulative research and development (R&D) to complete a lengthy process, and we study whether firms patent intermediate results or release them in Open Source. A patent holder obtains a larger reward in the market, but since in equilibrium it forecloses R&D, it remains alone to complete the process and so pays a larger cost than an Open Source firm. We have Open Source equilibria when R&D is highly complementary, R&D costs are large, and firms are sufficiently different and far from the frontier. We identify two market failures, in the forms of free riding and coordination failure, and we discuss public intervention.
Open-Source software in OR education
2010
24th European Conference on Operational Research (EURO XXIV). Lisboa, 11 a 14 de Julho de 2010 (Comunicação). This contribution will focus on Computational Tools of Open-Source Software in OR Education. Some educational experiences in the area of Forecasting; Simulation; Graphs and Networks; Decision Theory and Linear Programming based on: R 2.10.0, Scilab 5.1.1 and an Open Source Spreadsheet will be illustrated, with a brief reference to the acceptance of pupils and colleagues.
